Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Unless otherwise indicated, “we,” “us” and “our” mean SPX Corporation and its consolidated subsidiaries (“SPX”). We prepared the condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally required by accounting principles generally accepted in the United States (“GAAP”) can be condensed or omitted. The financial statements represent our accounts after the elimination of intercompany transactions and, in our opinion, include the adjustments (consisting only of normal and recurring items) necessary for their fair presentation. We account for investments in unconsolidated companies where we exercise significant influence but do not have control using the equity method. In determining whether we are the primary beneficiary of a variable interest entity (“VIE”), we perform a qualitative analysis that considers the design of the VIE, the nature of our involvement and the variable interests held by other parties to determine which party has the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and which party has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. We have an interest in a VIE, in which we are not the primary beneficiary, as a result of the sale of Balcke Dürr. See below and in Notes 3 and 16 for further discussion of the sale of Balcke Dürr. All other VIEs are considered immaterial, individually and in aggregate, to our condensed consolidated financial statements. Planned Wind-Down of SPX Heat Transfer Business During the second quarter of 2018, as a continuation of our strategic shift away from power generation end markets, we initiated a plan to wind-down the SPX Heat Transfer (“Heat Transfer”) business within our Engineered Solutions reportable segment. In connection with the planned wind-down, we recorded charges of $2.0 in our second quarter 2018 operating results, with $0.9 related to the write-down of inventories (included in “Cost of products sold”), $0.6 related to the impairment of machinery and equipment, and $0.5 related to severance costs (both included in “Special charges, net”). Additional severance costs were recorded to “Special charges, net” during the three months ended September 29, 2018 of $0.8. In addition, and as part of the wind-down, we sold certain intangible assets of the Heat Transfer business for net cash proceeds of $4.8, which resulted in a gain of less than $0.1 within our second quarter 2018 operating results. We anticipate completing the wind-down by the end of the first quarter of 2019. Acquisition of Cues On June 7, 2018, we completed the acquisition of Cues, Inc. (“Cues”), a manufacturer of pipeline inspection and rehabilitation equipment, which significantly increases our presence in the pipeline inspection market. The acquisition was completed through the purchase of all of the issued and outstanding shares of Cues’ parent company for a purchase price of $166.2, net of cash acquired of $20.6. Cues had revenues of approximately $84.0 for the twelve months prior to the acquisition. The assets acquired and liabilities assumed have been recorded at preliminary estimates of fair value as determined by management, based on information currently available and on current assumptions as to future operations and are subject to change upon completion of acquisition accounting. The post-acquisition operating results of Cues are reflected within our Detection and Measurement reportable segment. See Note 3 for additional details on the Cues acquisition. Acquisition of Schonstedt On March 1, 2018, we completed the acquisition of Schonstedt Instrument Company (“Schonstedt”), a manufacturer and distributor of magnetic locator products used for locating underground utilities and other buried objects, for a purchase price of $16.4, net of cash acquired of $0.3. Schonstedt had revenues of approximately $9.0 for the twelve months prior to the acquisition. The assets acquired and liabilities assumed have been recorded at preliminary estimates of fair value as determined by management, based on information currently available and on current assumptions as to future operations, and are subject to change upon completion of acquisition accounting. The post-acquisition operating results of Schonstedt are reflected within our Detection and Measurement reportable segment. Sale of Balcke Dürr On December 30, 2016, we completed the sale of Balcke Dürr to a subsidiary of mutares AG (the “Buyer”). During the first quarter of 2017, we reduced the net loss associated with the sale of Balcke Dürr by $7.2, with such amount recorded to “Gain on disposition of discontinued operations, net of tax.” The reduction was comprised of an additional income tax benefit recorded for the sale of $8.4, partially offset by adjustments to liabilities retained in connection with the sale, net of tax, of $1.2. During the second quarter of 2017, we increased the net loss associated with the sale of Balcke Dürr by $0.4, with the increase resulting from adjustments to liabilities retained in connection with the sale. On April 30, 2018, we reached a settlement with the Buyer on the amount of cash and working capital at the closing date, as well as on various other matters, for a net payment from the Buyer in the amount of Euro 3.0 (with Euro 2.0 received in May 2018 and Euro 1.0 in July 2018). The settlement resulted in a gain, net of tax, of $3.8, which was recorded to “Gain (loss) on disposition of discontinued operations, net of tax” during the second quarter of 2018. See Note 3 for information on discontinued operations. Other Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from these estimates. The unaudited information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2017. Interim results are not necessarily indicative of full year results. We have reclassified certain prior year amounts to conform to the current year presentation. Unless otherwise indicated, amounts provided in these Notes pertain to continuing operations only. See Note 3 for information on discontinued operations. We establish actual interim closing dates using a fiscal calendar, which requires our businesses to close their books on the Saturday closest to the end of the first calendar quarter, with the second and third quarters being 91 days in length. Our fourth quarter ends on December 31. The interim closing dates for the first, second and third quarters of 2018 are March 31, June 30 and September 29, compared to the respective April 1, July 1 and September 30, 2017 dates. We had one less day in the first quarter of 2018 and will have one more day in the fourth quarter of 2018 than in the respective 2017 periods. We do not believe the one less day during the first quarter of 2018 had a material impact on our consolidated operating results for the first nine months of 2018, when compared to the consolidated operating results for the first nine months of 2017.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

NEW ACCOUNTING PRONOUNCEMENTS

The following is a summary of new accounting pronouncements that apply or may apply to our business.

ASC Topic 606

In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new standard on revenue recognition (Accounting Standards Codification “ASC” 606) that outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASC 606 contains a five-step approach that entities will apply to determine the measurement of revenue and timing of when it is recognized, including (i) identifying the contract(s) with a customer, (ii) identifying the separate performance obligations in the contract, (iii) determining the transaction price, (iv) allocating the transaction price to separate performance obligations, and (v) recognizing revenue when (or as) each performance obligation is satisfied. ASC 606 also requires a number of quantitative and qualitative disclosures intended to enable users of the financial statements to understand the nature, amount, timing, and uncertainty of revenue, and the related cash flows. Effective January 1, 2018, we adopted ASC 606 using the modified retrospective transition approach for all contracts not completed as of the date of adoption. The modified retrospective transition approach recognizes any changes as of the beginning of the year of initial application (i.e., as of January 1, 2018) through retained earnings, with no restatement of comparative periods.

The only significant change in revenue recognition as a result of the adoption of ASC 606 relates to our power transformer business. Under ASC 606, revenues for our power transformer business are being recognized over time, while under previous revenue recognition guidance (ASC 605), revenues for power transformers were recognized at a point in time. See Note 4 for further discussion of our revenue recognition principles and the post adoption impact of ASC 606.

Summarized below is the impact of the initial application of ASC 606 on our January 1, 2018 condensed consolidated balance sheet:

Other Accounting Pronouncements

In February 2016, the FASB issued an amendment to existing guidance that requires lessees to recognize assets and liabilities for the rights and obligations created by long-term leases. In addition, this amendment requires new qualitative and quantitative disclosures about leasing arrangements. This standard is effective for annual reporting periods beginning on or after December 15, 2018 for public business entities, and interim periods within those annual reporting periods. Early adoption is permitted, and adoption must be applied on a modified retrospective basis. We are executing an implementation plan and are analyzing data to further assess the impact of this amendment on our consolidated financial statements. It is anticipated that the adoption will result in additional assets and liabilities on our consolidated balance sheet due to the recognition of lease rights and obligations. However, we do not expect the adoption to have a material impact to our consolidated statement of operations and comprehensive income or consolidated statement of cash flows.

In August 2016, the FASB issued an amendment to existing guidance to reduce diversity in practice in how certain cash receipts and cash payments are presented in the statement of cash flows. This amendment provides clarification on eight specific cash flow presentation issues. The issues include, but are not limited to, debt prepayment or extinguishment costs, settlement of zero-coupon debt, proceeds from the settlement of insurance claims, and cash receipts from payments on beneficial interests in securitization transactions. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods, and is to be applied retrospectively. We adopted this guidance during the first quarter of 2018, with such adoption having no material impact to our condensed consolidated financial statements.

In October 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-16, which removes the prohibition in ASC 740 against the immediate recognition of the current and deferred income tax effects of intra-entity transfers of assets other than inventory. ASU 2016-16 is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. The requirements of ASU 2016-16 are to be applied on a modified retrospective basis, which entails recognizing the initial effect of adoption in retained earnings. We adopted ASU 2016-16 as of January 1, 2018, which resulted in an increase of our retained deficit of $0.2.

In January 2017, the FASB issued an amendment to simplify the subsequent measurement of goodwill by removing the second step of the two-step impairment test. The amendment requires that an entity recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. This amendment is effective for annual reporting periods beginning after December 31, 2019, including interim periods within those annual reporting periods. Early adoption is permitted. The impact of this amendment on our consolidated financial statements will depend on the results of future goodwill impairment tests.

In March 2017, the FASB issued an amendment to revise the presentation of net periodic pension and postretirement benefit cost. The amendment requires the service cost component to be presented separately from the other components of net periodic pension and postretirement benefit cost. Service cost is required to be presented with other employee compensation costs within operating income. The other components of net periodic pension and postretirement benefit cost, such as interest cost, expected return on plan assets, amortization of prior service cost/credits, and gains or losses, are required to be separately presented outside of operating income. This amendment is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods, with the financial statement presentation requirements of the amendment applied retrospectively. We adopted this guidance during the first quarter of 2018, resulting in non-service pension and postretirement costs being presented outside of operating income within the accompanying condensed consolidated statements of operations. In connection with the adoption of this guidance, we reclassified $1.5 and $(0.9) of net periodic pension and postretirement benefit income (expense) from “Selling, general and administrative” expenses to “Other income (expense), net” within the accompanying condensed consolidated statements of operations for the three and nine months ended September 30, 2017, respectively. See Note 10 for details of our pension and postretirement expense.

In August 2017, the FASB issued significant amendments to hedge accounting. The FASB’s new guidance will make more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amends the presentation and disclosure requirements and changes how companies assess effectiveness. It is intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The amendments can be adopted immediately in any interim or annual period (including the current period). The mandatory effective date for calendar year-end public companies is January 1, 2019. We are currently evaluating the effect this amendment will have on our consolidated financial statements.

In February 2018, the FASB amended its guidance for reporting comprehensive income to reflect the potential impacts of the reduction in the corporate tax rate resulting from the Tax Cuts and Jobs Act (the “Act”). The amendment gives the option of reclassifying the stranded tax effects within accumulated other comprehensive income (“AOCI”) to retained earnings during the fiscal year or quarter in which the effect of the lower tax rate is recorded. The amendment is effective for years beginning after December 15, 2018, with early adoption permitted. We adopted this guidance as of January 1, 2018, which resulted in an increase of our retained deficit of $4.8.

AQUISITIONS AND DISCONTINUED OPERATIONS

ACQUISITIONS AND DISCONTINUED OPERATIONS

Acquisition of Cues

As indicated in Note 1, on June 7, 2018, we completed the acquisition of Cues for $166.2, net of cash acquired of $20.6. We financed the acquisition with available cash and borrowings under our senior credit and trade receivables financing arrangements. The assets acquired and liabilities assumed have been recorded at preliminary estimates of fair value as determined by management, based on information currently available and on current assumptions as to future operations and are subject to change upon completion of the acquisition method of accounting. The final determination of the fair values of certain assets and liabilities will be completed within the measurement period of up to one year from the acquisition date, as permitted under GAAP. The following is a summary of the recorded preliminary fair values of the assets acquired and liabilities assumed for Cues as of June 7, 2018:



Assets acquired:
Current assets, including cash and equivalents of $20.6	$	72.8
Property, plant and equipment	7.4
Goodwill	46.6
Intangible assets	79.5
Other assets	2.7
Total assets acquired	209.0

Current liabilities assumed	8.4
Non-current liabilities assumed	13.8

Net assets acquired	$	186.8

The identifiable intangible assets acquired consist of a trademark, customer backlog, customer relationships, and technology of $27.6, $0.8, $42.6, and $8.5, respectively, with such amounts based on a preliminary assessment of the related fair values. We expect to amortize the customer backlog, customer relationships, and technology assets over 0.5, 12.0, and 11.0 years, respectively.

We acquired gross receivables of $13.6, which had a fair value at the acquisition date of $13.2 based on our estimates of cash flows expected to be recovered.

The qualitative factors that comprise the recorded goodwill include expected synergies from combining our existing inspection equipment operations with those of Cues, expected market growth for Cues’ existing operations, and various other factors. We expect none of this goodwill or the intangible assets described above to be deductible for tax purposes.

We recognized revenues and net losses for Cues of $24.2 and $0.0, and $31.1 and $0.8, respectively, for the three and nine months ended September 29, 2018 with the net loss driven by charges of $2.5 and $4.1 for the three and nine months ended September 29, 2018, respectively, associated with the excess fair value (over historical cost) of inventory acquired which has been subsequently sold. During the three and nine months ended September 29, 2018, we incurred acquisition related costs for Cues of $0.5 and $2.2, respectively, which have been recorded to “Selling, general and administrative” within our condensed consolidated statements of operations.

The following unaudited pro forma information presents our results of operations for the three and nine months ended September 29, 2018 and September 30, 2017, respectively, as if the acquisition of Cues had taken place on January 1, 2017. The unaudited pro forma financial information is not intended to represent or be indicative of our consolidated results of operations that would have been reported had the acquisition been completed as of the date presented, and should not be taken as representative of our future consolidated results of operations. The pro forma results include estimates and assumptions that management believes are reasonable; however, these results do not include any anticipated cost savings or expenses of the planned integration of Cues. These pro forma results of operations have been prepared for comparative purposes only and include additional interest expense on the borrowings required to finance the acquisition, additional depreciation and amortization expense associated with fair value adjustments to the acquired property, plant and equipment and intangible assets, the removal of charges associated with the excess fair value (over historical cost) of inventory acquired and subsequently sold, the removal of professional fees incurred in connection with the transaction, and the related income tax effects.

Acquisition of Schonstedt

As indicated in Note 1, on March 1, 2018, we completed the acquisition of Schonstedt for $16.4, net of cash acquired of $0.3. The pro forma effects of the Schonstedt acquisition are not material to our consolidated results of operations.

Discontinued Operations

During the first quarter of 2017, we reduced the net loss associated with the sale of Balcke Dürr by $7.2. The reduction in the net loss was comprised of an additional income tax benefit recorded for the sale of $8.4, partially offset by the impact of adjustments to liabilities retained in connection with the sale, net of tax, of $1.2. During the second quarter of 2017, we increased the net loss associated with the sale of Balcke Dürr by $0.4, with the increase resulting from adjustments to liabilities retained in connection with the sale.

As indicated in Note 1, during the second quarter of 2018, we reached a settlement with the Buyer on the amount of cash and working capital at the closing date, as well as on various other matters. The settlement resulted in a gain, net of tax, of $3.8, which was recorded to “Gain (loss) on disposition of discontinued operations, net of tax” during the second quarter of 2018.

In addition to the adjustments to the net loss related to the Balcke Dürr sale, we recognized a net loss of $0.2 and $0.7 during the three and nine months ended September 29, 2018, respectively, and net income (losses) of $0.3 and $(0.1) during the three and nine months ended September 30, 2017, respectively, resulting primarily from revisions to liabilities retained from businesses discontinued prior to 2016.

For the three and nine months ended September 29, 2018 and September 30, 2017, the table below presents a reconciliation of discontinued operations activity to the related amounts in the condensed consolidated statements of operations:

Revenue from Contract with Customer [Abstract]

Revenue from Contracts

REVENUES FROM CONTRACTS

As indicated in Note 2, effective January 1, 2018, we adopted ASC 606 under the modified retrospective transition approach. As a result, for periods prior to 2018, revenue continues to be presented based on prior guidance. Summarized below is our policy for recognizing revenue, as well as the various other disclosures required by ASC 606.

ASC 606 Policy

Performance Obligations - Certain of our contracts are comprised of multiple deliverables, which can include hardware and software components, installation, maintenance, and extended warranties. For these contracts, we evaluate whether these deliverables represent separate performance obligations as defined by ASC 606. In some cases, a customer contracts with us to integrate a complex set of tasks and components into a single project or capability (even if the single project results in the delivery of multiple units). Hence, the entire contract is treated as a single performance obligation. In contrast, we may promise to provide distinct goods or services within a contract, in which case we separate the contract into more than one performance obligation. If a contract is separated into more than one performance obligation, we allocate the total transaction price to each performance obligation in an amount based on the estimated relative standalone selling prices of the promised goods or services underlying each performance obligation. In cases where we sell standard products with observable standalone selling prices, these selling prices are used to determine the standalone selling price. In cases where we sell a customized customer specific solution, we typically use the expected cost plus margin approach to estimate the standalone selling price of each performance obligation. Sales taxes and other usage-based taxes are excluded from revenue.

Remaining performance obligations represent performance obligations that have yet to be satisfied. As a practical expedient, we do not disclose performance obligations that are (i) part of a contract that has an original expected duration of less than one year (this encompasses substantially all contracts with customers in the HVAC and Detection and Measurement reportable segments) and/or (ii) satisfied in a manner consistent with our right to consideration from the customer (i.e., revenue is recognized as value is transferred). Performance obligations for contracts with an original duration in excess of one year that have yet to be satisfied as of the end of a period primarily relate to our large process cooling systems and large South African projects, as well as certain of our bus fare collection systems. As of September 29, 2018, the aggregate amount allocated to remaining performance obligations after the effect of practical expedients was $53.9. We expect to recognize revenue on approximately 70% and 91% of the remaining performance obligations over the next 12 and 24 months, respectively, with the remaining recognized thereafter.

Options - We offer options within certain of our contracts to purchase future goods or services. To the extent the option provides a material right to a future benefit (i.e., future goods and services at a discount from the relative standalone selling price), we separate the material right as a performance obligation and adjust the standalone selling price of the other performance obligations within the contract. When determining the relative standalone selling price of the option, we first determine the incremental discount that the customer would receive by exercising the option and then adjust that value based on the probability of option exercise (based, where possible, on historical experience). Revenue is recognized for the option as either the option is exercised or when it expires.

Contract Combination and Modification - We assess each contract at its inception to determine whether it should be combined with other contracts for revenue recognition purposes. When making this determination, we consider factors such as whether two or more contracts with a customer were negotiated at or near the same time or were negotiated with an overall profit objective. Contracts are sometimes modified for changes in contract specifications, scope, or price (or a combination of these). Contract modifications for goods or services that are not distinct within the context of the contract (generally associated with specification changes in our engineered solutions product lines) are accounted for as part of the existing contract. Contract modifications for goods or services that are distinct (i.e., adding or subtracting distinct goods or services) are accounted for as either a termination of the existing contract and the creation of a new contract (where the goods or services are not priced at their standalone selling price), or the creation of separate contract (where the goods or services are priced at their standalone selling price).

Variable Consideration - We determine the transaction price for each contract based on the consideration we expect to receive for the products or services being provided under the contract. For contracts where a portion of the price may vary, we estimate the variable consideration at the amount to which we expect to be entitled, which is included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur. We analyze the risk of a significant revenue reversal and, if necessary, constrain the amount of variable consideration recognized in order to mitigate this risk. Variable consideration primarily pertains to late delivery penalties, unapproved change orders and claims (levied by us and /or against us), and index-based pricing. Actual amounts of consideration ultimately received may differ from our estimates. If actual results vary from our estimates, we will adjust these estimates, which would affect revenue and earnings in the period such variances become known.

As noted above, the nature of our contracts gives rise to several types of variable consideration, including unapproved change orders and claims. We include in our contract estimates additional revenue for unapproved change orders or claims against the customer when we believe we have an enforceable right to the unapproved change order or claim, the amount can be reliably estimated, and the above criteria have been met. In evaluating these criteria, we consider the contractual/legal basis for the claim, the cause of any additional costs incurred, the reasonableness of those costs, and the objective evidence available to support the claim. These estimates are also based on historical award experience. At September 29, 2018, the aggregate revenues related to our large power projects in South Africa included approximately $38.4 related to claims and unapproved change orders. See Note 14 for additional details on our large power projects in South Africa.

Returns, Customer Sales Incentives and Warranties - We have certain arrangements that require us to estimate, at the time of sale, the amounts of variable consideration that should be excluded from revenue as (i) certain amounts are not expected to be collected from customers and/or (ii) the product may be returned. We principally rely on historical experience, specific customer agreements, and anticipated future trends to estimate these amounts at the time of shipment and to reduce the transaction price. These arrangements include volume rebates, which are estimated using the most likely amount method, as well as early payment discounts and promotional and advertising allowances, which are estimated using the expected value method. We primarily offer assurance-type standard warranties that the product will conform to published specifications for a defined period of time after delivery. These types of warranties do not represent separate performance obligations. We establish provisions for estimated returns and warranties primarily based on contract terms and historical experience, using the expected value method. Certain businesses separately offer extended warranties, which are considered separate performance obligations.

Contract Costs - We have elected to apply the practical expedient provided under ASC 606 which allows an entity to expense incremental costs of obtaining or fulfilling a contract when incurred if the amortization period of the asset that the entity otherwise would have recorded is one year or less. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as fulfillment costs and are included in cost of products sold. The net asset recorded for incremental costs incurred to obtain or fulfill contracts, after consideration of the practical expedient mentioned above, is not material to our condensed consolidated financial statements.

Nature of Goods and Services, Satisfaction of Performance Obligations, and Payment Terms

Our HVAC product lines include package cooling towers, residential and commercial boilers, and comfort heating and ventilation products. Performance obligations for our HVAC product lines relate primarily to the delivery of equipment and components, with satisfaction of these performance obligations occurring at the time of shipment or delivery (i.e., control is transferred at a point in time). The typical length of a contract is one to three months and payment terms are generally 15-60 days after shipment to the customer.

Our detection and measurement product lines include underground pipe and cable locators, inspection and rehabilitation equipment, bus fare collection systems, signal monitoring, and obstruction lighting. Performance obligations for these product lines relate to delivery of equipment and components, installation and other short-term services, long-term maintenance and software subscription services. Performance obligations for equipment and components are satisfied at the time of shipment or delivery (i.e., control is transferred at a point in time). Performance obligations for installation and other short-term services are satisfied over time as the installation or service is performed. Performance obligations for maintenance and software subscription services are satisfied over time, with the related revenue recorded evenly throughout the contract service period as this method best depicts how control of the service is transferred. Payment terms for equipment and components are typically 30 to 60 days after shipment or delivery, while payment for services typically occurs at completion for shorter-term engagements (less than three months in duration) and throughout the service period for longer-term engagements (generally greater than three months in duration). These product lines have varying contract lengths ranging from one to eighteen months (with the longer term contracts generally associated with our bus fare collection systems and signal monitoring products lines), with the typical duration being one to three months.

Our engineered solutions product lines include medium and large power transformers, process cooling equipment and heat exchangers, as well as two large power plant contracts in our South African business. Performance obligations for these product lines relate to delivery of equipment and components, construction and reconstruction of cooling towers and other components, and providing installation, replacement/spare parts, and various other services. For these product lines, our customers typically contract with us to provide a customer-specific solution. The customer typically controls the work in process due to contractual termination clauses whereby we have an enforceable right to recovery of cost incurred including a reasonable profit for work performed to date on products or services that do not have an alternative use to us. Additionally, certain projects are performed on customer sites such that the customer controls the asset as it is created or enhanced. As such, performance obligations for these product lines are generally satisfied over time, with the related revenue recorded based on the percentage of costs incurred to date for each contract to the estimated total costs for such contract at completion, as this method best depicts how control of the product or service is being transferred. Revenue for sales of certain engineered components and all replacement/spare parts is recognized upon shipment or delivery (i.e., at a point in time). The length of customer contract is generally 6-12 months for our power transformers business and 6-18 months for our process cooling and heat exchanger businesses. The large contracts in our South African business relate to the construction of two large power plants that have a length in excess of 10 years. Payments on longer-term contracts are generally commensurate with milestones defined in the related contract, while payments for the replacement/spare parts contracts typically occur 30 to 60 days after delivery.

Customer prepayments, progress billings, and retention payments are customary in certain of our project-based businesses, generally for our engineered solutions product lines and, to a lesser extent, our detection and measurement product lines. Customer prepayments, progress billings, and retention payments are not considered a significant financing component because they are intended to protect either the customer or ourselves in the event that some or all of the obligations under the contract are not completed. Additionally, most contract assets are expected to convert to accounts receivable, and contract liabilities are expected to convert to revenue, within one year. As such, after applying the practical expedient to exclude potential significant financing components that are less than one year in duration, we do not have any such financing components.

Disaggregated Revenues

We disaggregate revenue from contracts with customers by major product line and based on the timing of recognition for each of our reportable segments, as we believe such disaggregation best depicts how the nature, amount, timing, and uncertainty of our revenues and cash flows are effected by economic factors, with such disaggregation presented below for the three and nine months ended September 29, 2018:

Contract Balances

Our customers are invoiced for products and services at the time of delivery or based on contractual milestones, resulting in outstanding receivables with payment terms from these customers (“Contract Accounts Receivable”). In some cases, the timing of revenue recognition, particularly for revenue recognized over time, differs from when such amounts are invoiced to customers, resulting in a contract asset (revenue recognition precedes the invoicing of the related revenue amount) or a contract liability (payment from the customer precedes recognition of the related revenue amount). Contract assets and liabilities are generally classified as current. On a contract-by-contract basis, the contract assets and contract liabilities are reported net within our condensed consolidated balance sheet. Our contract balances consisted of the following as of September 29, 2018 and January 1, 2018:



Contract Balances	September 29, 2018			January 1, 2018 ⁽¹⁾			Change
Contract Accounts Receivable ⁽²⁾	$	249.0		$	222.9		$	26.1
Contract Assets	90.2			70.7			19.5
Contract Liabilities - current	(75.3		)	(86.9		)	11.6
Contract Liabilities - non-current ⁽³⁾	(2.0		)	—			(2.0		)
Net contract balance	$	261.9		$	206.7		$	55.2

_____________________

⁽¹⁾ See Note 2 for the impact of the change at January 1, 2018 as a result of the adoption of ASC 606.

⁽²⁾ Included in “Accounts receivable, net” within the accompanying condensed consolidated balance sheet.

⁽³⁾ Included in “Other long-term liabilities” within the accompanying condensed consolidated balance sheet.

The $55.2 increase in our net contract balance from January 1, 2018 to September 29, 2018 was due primarily to revenue recognized during the period, partially offset by cash payments received from customers during the period.

During 2018, we recognized revenues of $6.8 and $56.7 during the three and nine months ended September 29, 2018, respectively, related to our contract liabilities at January 1, 2018.

Impact of ASC 606 Adoption

Summarized below and on the following page is a comparison of our condensed consolidated statements of operations and comprehensive income for the three and nine months ended September 29, 2018 and condensed consolidated balance sheet as of September 29, 2018 as prepared under the provisions of ASC 606 to a presentation of these financial statements under the prior revenue recognition guidance. As previously discussed, the most significant impact of adopting ASC 606 relates to our power transformer business where, under ASC 606, revenues for power transformers are now being recorded over time versus at a point in time under the prior revenue recognition guidance. The initial transition to ASC 606 resulted in a reduction of inventory and deferred revenue (previously presented within “Accrued expenses”) and an increase to contract assets, as indicated in Note 2. Contract assets and contract liabilities are now separately presented within our condensed consolidated balance sheet (previously included in “Accounts receivable, net” and “Accrued expenses”, respectively). Additionally, and as noted below, the difference in revenue and earnings under prior revenue recognition guidance during the three and nine months ended September 29, 2018 is due primarily to the timing of power transformer deliveries.

Segment Reporting [Abstract]

INFORMATION ON REPORTABLE SEGMENTS

We are a global supplier of highly specialized, engineered solutions with operations in 14 countries and sales in over 100 countries around the world.

We have aggregated our operating segments into the following three reportable segments: HVAC, Detection and Measurement, and Engineered Solutions. The factors considered in determining our aggregated segments are the economic similarity of the businesses, the nature of products sold or services provided, production processes, types of customers, distribution methods, and regulatory environment. In determining our segments, we apply the threshold criteria of the Segment Reporting Topic of the Codification. Operating income or loss for each of our segments is determined before considering impairment and special charges, long-term incentive compensation and other indirect corporate expenses. This is consistent with the way our chief operating decision maker evaluates the results of each segment.

HVAC Reportable Segment

Our HVAC reportable segment engineers, designs, manufactures, installs and services cooling products for the HVAC and industrial markets, as well as boilers and comfort heating and ventilation products for the residential and commercial markets. The primary distribution channels for the segment’s products are direct to customers, independent manufacturing representatives, third-party distributors, and retailers. The segment serves a customer base in North America, Europe, and Asia Pacific.

Detection and Measurement Reportable Segment

Our Detection and Measurement reportable segment engineers, designs, manufactures and installs underground pipe and cable locators, inspection and rehabilitation equipment, bus fare collection systems, signal monitoring equipment, and obstruction lighting. The primary distribution channels for the segment’s products are direct to customers and third-party distributors.

_________________________

⁽¹⁾ As further discussed in Note 14, during the third quarter of 2018 and second quarter of 2017, we made revisions to our expected revenues and profits on our large power projects in South Africa. As a result of these revisions, we reduced revenue and segment income by $2.7 and $4.7, respectively, for the three and nine months ended September 29, 2018 and $13.5 and $22.9, respectively, for the nine months ended September 30, 2017.

⁽²⁾ During the third quarter of 2017, we settled a contract that had been suspended and then ultimately canceled by a customer for cash proceeds of $9.0 and other consideration. In connection with the settlement, we recorded a gain of $10.2 during the quarter within our Engineered Solutions reportable segment.

We perform our annual goodwill impairment testing during the fourth quarter in conjunction with our annual financial planning process, with such testing based primarily on events and circumstances existing as of the end of the third quarter. In addition, we test goodwill for impairment on a more frequent basis if there are indications of potential impairment. A significant amount of judgment is involved in determining if an indication of impairment has occurred between annual testing dates. Such indication may include: a significant decline in expected future cash flows; a significant adverse change in legal factors or the business climate; unanticipated competition; and a more likely than not expectation of selling or disposing all, or a portion, of a reporting unit.

We perform our annual trademarks impairment testing during the fourth quarter, or on a more frequent basis, if there are indications of potential impairment. The fair values of our trademarks are determined by applying estimated royalty rates to projected revenues, with the resulting cash flows discounted at a rate of return that reflects current market conditions (fair value based on unobservable inputs - Level 3, as defined in Note 16). The primary basis for these projected revenues is the annual operating plan for each of the related businesses, which is prepared in the fourth quarter of each year.

Retirement Benefits [Abstract]

EMPLOYEE BENEFIT PLANS

In July 2014, we discontinued our sponsorship of post-65 age healthcare plans, effective January 1, 2015, which resulted in eligible retirees being transitioned to coverage in the individual healthcare insurance market that we subsidize through health reimbursement accounts. In November 2014, a lawsuit was filed challenging certain aspects of this action. In September 2017, we received a favorable ruling related to the lawsuit. During the third quarter of 2017, in connection with the favorable ruling, we reduced our unfunded liability related to postretirement benefits by $26.8. The offset for the reduction of the unfunded liability was recorded to accumulated other comprehensive income and represents unrecognized prior service credits. These unrecognized prior service credits are being recorded to net periodic postretirement benefit (income) expense over a period of approximately eight years. In addition, we remeasured our unfunded liability related to postretirement benefits, which resulted in a gain within net periodic postretirement benefit expense and a reduction of the unfunded liability of $2.6 during the third quarter of 2017.

Net periodic benefit expense (income) for our pension and postretirement plans include the following components:

Total long-term debt	$	349.3								$	340.6

___________________________


⁽¹⁾	The term loan is repayable in quarterly installments of 1.25% of the initial loan amount of $350.0, beginning in the first quarter of 2019, with the remaining balance payable in full on December 19, 2022. Balances are net of unamortized debt issuance costs of $2.0 and $2.3 at September 29, 2018 and December 31, 2017, respectively.


⁽²⁾	Under this arrangement, we can borrow, on a continuous basis, up to $50.0, as available. At September 29, 2018, we had $17.4 of available borrowing capacity under this facility after giving effect to outstanding borrowings of $27.0. Borrowings under this arrangement are collateralized by eligible trade receivables of certain of our businesses.

⁽³⁾

Primarily includes balances under a purchase card program of $2.4 and $2.8, capital lease obligations of $1.9 and $2.1, and borrowings under a line of credit in China totaling $2.9 and $4.1 at September 29, 2018 and December 31, 2017, respectively. The purchase card program allows for payment beyond the normal payment terms for goods and services acquired under the program. As this arrangement extends the payment of these purchases beyond their normal payment terms through third-party lending institutions, we have classified these amounts as short-term debt.


⁽⁴⁾	“Other” primarily includes debt assumed, foreign currency translation on any debt instruments denominated in currencies other than the U.S. dollar, and the impact of amortization of debt issuance costs associated with the term loan.

Senior Credit Facilities

A detailed description of our senior credit facilities is included in our 2017 Annual Report on Form 10-K.

At September 29, 2018, we had $32.0 and $135.0 of outstanding letters of credit issued under our revolving credit and our foreign credit instrument facilities of our senior credit agreement, respectively.

The weighted-average interest rate of outstanding borrowings under our senior credit agreement was approximately 3.93% at September 29, 2018.

At September 29, 2018, we were in compliance with all covenants of our senior credit agreement.

DERIVATIVE FINANCIAL INSTRUMENTS	9 Months Ended
DERIVATIVE FINANCIAL INSTRUMENTS	Sep. 29, 2018
Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Interest Rate Swaps During the second quarter of 2016, we entered into an interest rate swap agreement to hedge the interest rate risk on our then existing variable rate term loan. As a result of amending our senior credit agreement on December 19, 2017, these swaps (“Old Swaps”) no longer qualified for hedge accounting. On March 8, 2018, we extinguished the Old Swaps and entered into a new interest rate swap agreement (the “New Swaps”) to hedge the interest rate risk on the variable interest rate borrowings under our senior credit agreement. The New Swaps, which we have designated and are accounting for as cash flow hedges, have an initial notional amount of $260.0 and maturities through December 2021 and effectively convert a portion of the borrowings under our senior credit agreement to a fixed rate of 2.535%, plus the applicable margin. As of September 29, 2018, the aggregate notional amounts of the New Swaps was $260.0 and the unrealized gain, net of tax, recorded in AOCI was $0.2. In addition, as of September 29, 2018, we recorded a long-term asset of $0.3 to recognize the fair value of the New Swaps. Changes in fair value for the New Swaps are reclassified into earnings as a component of interest expense, when the forecasted transaction impacts earnings. Currency Forward Contracts and Currency Forward Embedded Derivatives From time to time, we enter into forward contracts to manage the exposure on contracts with forecasted transactions denominated in non-functional currencies and to manage the risk of transaction gains and losses associated with assets/liabilities denominated in currencies other than the functional currency of certain subsidiaries (“FX forward contracts”). In addition, some of our contracts contain currency forward embedded derivatives (“FX embedded derivatives”), because the currency of exchange is not “clearly and closely” related to the functional currency of either party to the transaction. Certain of our FX forward contracts are designated as cash flow hedges. To the extent these derivatives are effective in offsetting the variability of the hedged cash flows, changes in the derivatives’ fair value are not included in current earnings, but are included in AOCI. These changes in fair value are reclassified into earnings as a component of revenues or cost of products sold, as applicable, when the forecasted transaction impacts earnings. In addition, if the forecasted transaction is no longer probable, the cumulative change in the derivatives’ fair value is recorded as a component of “Other income (expense), net” in the period in which the transaction is no longer considered probable of occurring. To the extent a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period in which it occurs. We had FX forward contracts with an aggregate notional amount of $14.2 and $9.0 outstanding as of September 29, 2018 and December 31, 2017, respectively, with all of the $14.2 scheduled to mature within one year. We also had FX embedded derivatives with an aggregate notional amount of $0.6 and $1.1 at September 29, 2018 and December 31, 2017, respectively, with all of the $0.6 scheduled to mature within one year. There were no unrealized gains or losses recorded in AOCI related to FX forward contracts as of September 29, 2018 and December 31, 2017. The fair value of our FX forward contracts and FX embedded derivative instruments were not material in relation to our condensed consolidated balance sheets as of September 29, 2018 and December 31, 2017. Commodity Contracts From time to time, we enter into commodity contracts to manage the exposure on forecasted purchases of commodity raw materials. At September 29, 2018 and December 31, 2017, the outstanding notional amount of commodity contracts was 3.9 and 3.6 pounds of copper, respectively. We designate and account for these contracts as cash flow hedges and, to the extent these commodity contracts are effective in offsetting the variability of the forecasted purchases, the change in fair value is included in AOCI. We reclassify AOCI associated with our commodity contracts to cost of products sold when the forecasted transaction impacts earnings. As of September 29, 2018 and December 31, 2017, the fair value of these contracts were $0.7 (current liability) and $1.1 (current asset), respectively. The unrealized gains (losses), net of taxes, recorded in AOCI were $(0.5) and $0.8 as of September 29, 2018 and December 31, 2017, respectively. We anticipate reclassifying the unrealized losses as of September 29, 2018 to earnings over the next 12 months.

The weighted-average number of restricted stock shares/units and stock options excluded from the computation of diluted income per share because the assumed proceeds for these instruments exceed the average market value of the underlying common stock for the related period was 0.452 and 0.961, respectively, for the three months ended September 30, 2017, and 0.534 and 1.009, respectively, for the nine months ended September 30, 2017.

Long-Term Incentive Compensation

Long-term incentive compensation awards may be granted to certain eligible employees or non-employee directors. A detailed description of the awards granted prior to 2018 is included in our 2017 Annual Report on Form 10-K.

Awards granted on February 22, 2018 to executive officers and other members of senior management were comprised of performance stock units (“PSU’s”), stock options, time-based restricted stock units (“RSU’s”), and long-term cash awards, while other eligible employees were granted RSU’s and long-term cash awards. The PSU’s are eligible to vest at the end of a three-year performance period, with performance based on the total return of our stock over the three-year performance period against a peer group within the S&P 600 Capital Goods Index. Stock options and RSU’s vest ratably over the three-year period subsequent to the date of grant. Long-term cash awards are eligible to vest at the end of a three-year performance measurement period, with performance based on our achieving a target segment income amount over the three-year measurement period.

Effective May 15, 2018, we granted 0.023 RSU’s to our non-employee directors, which vest in their entirety immediately prior to the annual meeting of stockholders in May 2019.

Compensation expense within income from continuing operations related to long-term incentive awards totaled $4.3 and $3.6 for the three months ended September 29, 2018 and September 30, 2017, respectively and $12.4 and $10.4 for the nine months ended September 29, 2018 and September 30, 2017, respectively. The related tax benefit was $1.1 and $1.4 for the three months ended September 29, 2018 and September 30, 2017, respectively and $3.2 and $4.0 for the nine months ended September 29, 2018 and September 30, 2017.

CONTINGENT LIABILITIES AND OTHER MATTERS	9 Months Ended
CONTINGENT LIABILITIES AND OTHER MATTERS	Sep. 29, 2018
Commitments and Contingencies Disclosure [Abstract]
CONTINGENT LIABILITIES AND OTHER MATTERS	CONTINGENT LIABILITIES AND OTHER MATTERS General Numerous claims, complaints and proceedings arising in the ordinary course of business have been asserted or are pending against us or certain of our subsidiaries (collectively, “claims”). These claims relate to litigation matters (e.g., class actions and contracts, intellectual property, and competitive claims), environmental matters, product liability matters (predominately associated with alleged exposure to asbestos-containing materials), and other risk management matters (e.g., general liability, automobile, and workers’ compensation claims). Additionally, we may become subject to other claims of which we are currently unaware, which may be significant, or the claims of which we are aware may result in our incurring significantly greater loss than we anticipate. While we (and our subsidiaries) maintain property, cargo, auto, product, general liability, environmental, and directors’ and officers’ liability insurance and have acquired rights under similar policies in connection with acquisitions that we believe cover a significant portion of these claims, this insurance may be insufficient or unavailable (e.g., in the case of insurer insolvency) to protect us against potential loss exposures. Also, while we believe we are entitled to indemnification from third parties for some of these claims, these rights may be insufficient or unavailable to protect us against potential loss exposures. Our recorded liabilities related to these matters totaled $648.5 (including $605.3 for asbestos product liability matters) and $685.7 (including $641.2 for asbestos product liability matters) at September 29, 2018 and December 31, 2017, respectively. Of these amounts, $618.1 and $651.6 are included in “Other long-term liabilities” within our condensed consolidated balance sheets at September 29, 2018 and December 31, 2017, respectively, with the remainder included in “Accrued expenses.” The liabilities we record for these claims are based on a number of assumptions, including historical claims and payment experience and, with respect to asbestos claims, actuarial estimates of the future period during which additional claims are reasonably foreseeable. While we base our assumptions on facts currently known to us, they entail inherently subjective judgments and uncertainties. As a result, our current assumptions for estimating these liabilities may not prove accurate, and we may be required to adjust these liabilities in the future, which could result in charges to earnings. These variances relative to current expectations could have a material impact on our financial position and results of operations. Our asbestos-related claims are typical in certain of the industries in which we operate or pertain to legacy businesses we no longer operate. It is not unusual in these cases for fifty or more corporate entities to be named as defendants. We vigorously defend these claims, many of which are dismissed without payment, and the significant majority of costs related to these claims have historically been paid pursuant to our insurance arrangements. During the nine months ended September 29, 2018, our payments for asbestos-related matters, net of insurance recoveries of $26.9, were $5.3, which included cash proceeds of $5.5 received during the third quarter of 2018 related to a settlement reached with an insurance carrier. During the nine months ended September 30, 2017, our insurance recoveries for asbestos-related matters, net of payments of $36.8, were $2.3, which included cash proceeds received during the first quarter of 2017 of $8.5 related to a settlement reached with an insurance carrier. A significant increase in claims, costs and/or issues with existing insurance coverage (e.g., dispute with or insolvency of insurer(s)) could have a material adverse impact on our share of future payments related to these matters, and, as such, have a material impact on our financial position, results of operations and cash flows. We have recorded insurance recovery assets associated with the asbestos product liability matters, with such amounts totaling $558.5 and $590.9 at September 29, 2018 and December 31, 2017, respectively, and included in “Other assets” within our condensed consolidated balance sheets. These assets represent amounts that we believe we are or will be entitled to recover under agreements we have with insurance companies. The assets we record for these insurance recoveries are based on a number of assumptions, including the continued solvency of the insurers, and are subject to a variety of uncertainties. Our current assumptions for estimating these assets may not prove accurate, and we may be required to adjust these assets in the future, which could result in additional charges to earnings. These variances relative to current expectations could have a material impact on our financial position and results of operations. There were no changes in estimates associated with the liabilities and assets related to our asbestos product liability matters during the three and nine months ended September 29, 2018. During the nine months ended September 30, 2017, we recorded a charge of $3.0 to “Other income (expense), net” related to the settlement of a group of asbestos related claims. Large Power Projects in South Africa The business environment surrounding our large power projects in South Africa remains difficult, as our South African subsidiary, DBT Technologies (PTY) LTD (“DBT”), has experienced delays, cost over-runs, and various other challenges associated with a complex set of contractual relationships among the end customer, prime contractors, various subcontractors (including DBT and its subcontractors), and various suppliers. DBT currently is involved in a number of claim disputes relating to these challenges. DBT is pursuing various commercial alternatives for addressing these challenges, in attempt to mitigate our overall financial exposure. On October 30, 2018, a non-governmental business adjudicator in South Africa provided a decision on certain claims made against DBT by one of its subcontractors. As part of its decision, the adjudicator concluded that the subcontractor was entitled to payment of South African Rand 256.0 (or $18.1). We believe that the decision is invalid on numerous bases. Therefore, DBT intends to pursue all available legal recourse in the matter and DBT has already referred the matter to both an arbitration process and court proceedings. Specifically, we believe, among other things, that (i) the adjudicator lacked jurisdiction to decide the claims and (ii) these and other claims were previously settled and satisfied by way of a 2015 amendment to the contract between DBT and the subcontractor. Based on the reasons stated above, we have concluded that it is not probable that a loss has been incurred with respect to this matter and, therefore, a liability has not been recorded in our condensed consolidated financial statements. It is possible that an adverse result for any of these disputes could have a material effect on our condensed consolidated financial statements. During the third quarter of 2018 and the second quarter of 2017, we revised our estimates of revenues, costs, and profits associated with the projects due to higher than expected costs associated with (i) our efforts to accelerate completion of certain scopes of work, (ii) financial and other challenges facing certain of our subcontractors, and (iii) delays and other on-site productivity challenges. These revisions resulted in a charge to “Income (loss) from continuing operations before income taxes” of $4.7 during the three and nine months ended September 29, 2018 and $22.9 during the nine months ended September 30, 2017. The third quarter of 2018 charge is comprised of a reduction in revenue of $2.7 and an increase in cost of products sold of $2.0, while the second quarter of 2017 charge is comprised of a reduction in revenue of $13.5 and an increase in cost of products sold of $9.4. Over the past two years, we have implemented various initiatives that have reduced the risk associated with our large power projects in South Africa, including more recent steps to accelerate the timeline for completing certain portions of the projects. In addition, significant progress has occurred with regard to the projects, as we have now completed the majority of our contractual scope and are targeting to complete the remainder by the end of 2019. Although we believe that our current estimates of revenues, costs and profits relating to these projects are reasonable, it is possible that future revisions of such estimates could have a material effect on our condensed consolidated financial statements. Noncontrolling Interest in South African Subsidiary DBT has a Black Economic Empowerment shareholder (the “BEE Partner”) that holds a 25.1% noncontrolling interest in DBT. Under the terms of the shareholder agreement between the BEE Partner and SPX Technologies (PTY) LTD (“SPX Technologies”), the BEE Partner had the option to put its ownership interest in DBT to SPX Technologies, the majority shareholder of DBT, at a redemption amount determined in accordance with the terms of the shareholder agreement (the “Put Option”). The BEE Partner notified SPX Technologies of its intention to exercise the Put Option and, on July 6, 2016, an Arbitration Tribunal declared that the BEE Partner was entitled to South African Rand 287.3 in connection with the exercise of the Put Option, having not considered an amount due from the BEE Partner under a promissory note of South African Rand 30.3 held by SPX Technologies. As a result, we have reflected the net redemption amount of South African Rand 257.0 (or $18.1 and $20.9 at September 29, 2018 and December 31, 2017, respectively) within “Accrued expenses” on our condensed consolidated balance sheets, with the related offset recorded to “Paid-in capital” and “Accumulated other comprehensive income.” In August 2016, SPX Technologies applied to the High Court of South Africa (the “Court”) to have the Arbitration Tribunal’s ruling set aside. On January 22, 2018, the Court ruled in SPX Technologies’ favor and set aside the Arbitration Tribunal’s ruling. This ruling by the Court is subject to appeal by the BEE Partner. The BEE Partner has filed for leave to appeal the decision and SPX Technologies will continue to assert all legal defenses available to it. Litigation Matters We are subject to other legal matters that arise in the normal course of business. We believe these matters are either without merit or of a kind that should not have a material effect, individually or in the aggregate, on our financial position, results of operations or cash flows; however, we cannot assure you that these proceedings or claims will not have a material effect on our financial position, results of operations or cash flows. Environmental Matters Our operations and properties are subject to federal, state, local and foreign regulatory requirements relating to environmental protection. It is our policy to comply fully with all applicable requirements. As part of our effort to comply, we have a comprehensive environmental compliance program that includes environmental audits conducted by internal and external independent professionals, as well as regular communications with our operating units regarding environmental compliance requirements and anticipated regulations. Based on current information, we believe that our operations are in substantial compliance with applicable environmental laws and regulations, and we are not aware of any violations that could have a material effect, individually or in the aggregate, on our business, financial condition, and results of operations or cash flows. As of September 29, 2018, we had liabilities for site investigation and/or remediation at 28 sites (28 sites at December 31, 2017) that we own or control, or formerly owned and controlled. In addition, while we believe that we maintain adequate accruals to cover the costs of site investigation and/or remediation, we cannot provide assurance that new matters, developments, laws and regulations, or stricter interpretations of existing laws and regulations will not materially affect our business or operations in the future. Our environmental accruals cover anticipated costs, including investigation, remediation, and maintenance of clean-up sites. Our estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties. Accordingly, our estimates may change based on future developments, including new or changes in existing environmental laws or policies, differences in costs required to complete anticipated actions from estimates provided, future findings of investigation or remediation actions, or alteration to the expected remediation plans. It is our policy to revise an estimate once the revision becomes probable and the amount of change can be reasonably estimated. We generally do not discount our environmental accruals and do not reduce them by anticipated insurance recoveries. We take into account third-party indemnification from financially viable parties in determining our accruals where there is no dispute regarding the right to indemnification. In the case of contamination at offsite, third-party disposal sites, as of September 29, 2018, we have been notified that we are potentially responsible and have received other notices of potential liability pursuant to various environmental laws at 15 sites at which the liability has not been settled, of which 10 sites have been active in the past few years. These laws may impose liability on certain persons that are considered jointly and severally liable for the costs of investigation and remediation of hazardous substances present at these sites, regardless of fault or legality of the original disposal. These persons include the present or former owners or operators of the site and companies that generated, disposed of or arranged for the disposal of hazardous substances at the site. We are considered a “de minimis” potentially responsible party at most of the sites, and we estimate that our aggregate liability, if any, related to these sites is not material to our condensed consolidated financial statements. We conduct extensive environmental due diligence with respect to potential acquisitions, including environmental site assessments and such further testing as we may deem warranted. If an environmental matter is identified, we estimate the cost and either establish a liability, purchase insurance or obtain an indemnity from a financially sound seller; however, in connection with our acquisitions or dispositions, we may assume or retain significant environmental liabilities, some of which we may be unaware. The potential costs related to these environmental matters and the possible impact on future operations are uncertain due in part to the complexity of government laws and regulations and their interpretations, the varying costs and effectiveness of various clean-up technologies, the uncertain level of insurance or other types of recovery, and the questionable level of our responsibility. We record a liability when it is both probable and the amount can be reasonably estimated. In our opinion, after considering accruals established for such purposes, the cost of remedial actions for compliance with the present laws and regulations governing the protection of the environment are not expected to have a material impact, individually or in the aggregate, on our financial position, results of operations or cash flows. Self-insured Risk Management Matters We are self-insured for certain of our workers’ compensation, automobile, product and general liability, disability and health costs, and we believe that we maintain adequate accruals to cover our retained liability. Our accruals for risk management matters are determined by us, are based on claims filed and estimates of claims incurred but not yet reported, and generally are not discounted. We consider a number of factors, including third-party actuarial valuations, when making these determinations. We maintain third-party stop-loss insurance policies to cover certain liability costs in excess of predetermined retained amounts. The insurance may be insufficient or unavailable (e.g., because of insurer insolvency) to protect us against loss exposure.

INCOME TAXES	9 Months Ended
INCOME TAXES	Sep. 29, 2018
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES Uncertain Tax Benefits As of September 29, 2018, we had gross unrecognized tax benefits of $27.9 (net unrecognized tax benefits of $19.8). Of these net unrecognized tax benefits, $16.1 would impact our effective tax rate from continuing operations if recognized. We classify interest and penalties related to unrecognized tax benefits as a component of our income tax provision. As of September 29, 2018, gross accrued interest totaled $4.8 (net accrued interest of $3.7). As of September 29, 2018, we had no accrual for penalties included in our unrecognized tax benefits. Based on the outcome of certain examinations or as a result of the expiration of statutes of limitations for certain jurisdictions, we believe that within the next 12 months it is reasonably possible that our previously unrecognized tax benefits could decrease by up to $10.0. The previously unrecognized tax benefits relate to a variety of tax matters including deemed income inclusions, transfer pricing and various state matters. Other Tax Matters For the three months ended September 29, 2018, we recorded an income tax provision of $1.7 on $8.5 of pre-tax income from continuing operations, resulting in an effective rate of 20.0%. This compares to an income tax provision for the three months ended September 30, 2017 of $4.8 on $26.8 of pre-tax income from continuing operations, resulting in an effective rate of 17.9%. The most significant items impacting the income tax provision for the third quarter of 2017 were $5.0 of foreign losses generated during the period for which no tax benefit was recognized, as future realization of any such tax benefit is considered unlikely, and $4.1 of tax benefits related to various audit settlements, statute expirations, and other adjustments to liabilities for uncertain tax positions. For the nine months ended September 29, 2018, we recorded an income tax provision of $6.2 on $45.1 of pre-tax income from continuing operations, resulting in an effective rate of 13.7% This compares to an income tax provision for the nine months ended September 30, 2017 of $14.0 on $38.0 of pre-tax income from continuing operations, resulting in an effective rate of 36.8%. The most significant items impacting the income tax provision for the first nine months of 2018 were (i) tax benefits of $1.7 related to reductions in valuation allowances recorded against certain deferred tax assets and (ii) $1.0 of excess tax benefits resulting from stock-based compensation awards that vested during the year. The most significant items impacting the income tax provision for the first nine months of 2017 were (i) $34.6 of foreign losses generated during the period for which no benefit was recognized, as future realization of any such tax benefit is considered unlikely, and (ii) $4.1 of tax benefits related to various audit settlements, statute expirations, and other adjustments to liabilities for uncertain tax positions. On December 22, 2017, the Act was enacted which significantly changes U.S. income tax law for businesses. As a result of the reduction in the federal corporate income tax rate and other legislative changes in the Act, we revalued our net U.S. federal deferred tax assets, resulting in a provisional charge of $11.8 in the fourth quarter of 2017. During the first three quarters of 2018, we have continued to evaluate the impact of the Act and have recorded a net additional charge of $0.9 to revalue certain deferred tax assets. Given the significance of the number of changes required by the Act and the historical complexity of our global tax structure, we have yet to complete our analysis of the impact of the Act on our condensed consolidated financial statements. As a result, the above net charges are based on current estimates (i.e., provisional amounts). In addition, other adjustments may be necessary to our income tax accounts to properly reflect the impact of certain provisions of the Act that have not been contemplated. For example, the impact on the potential repatriation of certain foreign earnings has not been considered in our provisional amounts. As more guidance is issued and we better understand the full impact of the Act on our tax positions, we will finalize our analysis, with any resulting adjustments reflected in our consolidated financial results for the year ended December 31, 2018. We perform reviews of our income tax positions on a continuous basis and accrue for potential uncertain positions when we determine that an uncertain position meets the criteria of the Income Taxes Topic of the Codification. Accruals for these uncertain tax positions are recorded in “Income taxes payable” and “Deferred and other income taxes” in the accompanying condensed consolidated balance sheets based on the expectation as to the timing of when the matters will be resolved. As events change and resolutions occur, these accruals are adjusted, such as in the case of audit settlements with taxing authorities. The Internal Revenue Service (“IRS”) currently is performing an audit of our 2014 and 2015 federal income tax returns. We have filed our federal income tax returns for the 2016 and 2017 tax years and those returns are also subject to examination. With regard to all open tax years, we believe any contingencies are adequately provided for. State income tax returns generally are subject to examination for a period of three to five years after filing the respective tax returns. The impact on such tax returns of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. We have various state income tax returns in the process of examination. We believe any uncertain tax positions related to these examinations have been adequately provided for. We have various foreign income tax returns under examination. The most significant of these are in Germany for the 2010 through 2014 tax years. We believe that any uncertain tax positions related to these examinations have been adequately provided for. An unfavorable resolution of one or more of the above matters could have a material adverse effect on our results of operations or cash flows in the quarter and year in which an adjustment is recorded or the tax is due or paid. As audits and examinations are still in process, the timing of the ultimate resolution and any payments that may be required for the above matters cannot be determined at this time.

FAIR VALUE

9 Months Ended

Sep. 29, 2018

Fair Value Disclosures [Abstract]

FAIR VALUE

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In the absence of active markets for the identical assets or liabilities, such measurements involve developing assumptions based on market observable data and, in the absence of such data, internal information consistent with what market participants would use in a hypothetical transaction that occurs at the measurement date. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. Preference is given to observable inputs. These two types of inputs create the following fair value hierarchy:


•	Level 1 — Quoted prices for identical instruments in active markets.


•	Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.


•	Level 3 — Significant inputs to the valuation model are unobservable.

There were no changes during the periods presented to the valuation techniques we use to measure asset and liability fair values on a recurring or nonrecurring basis. There were no transfers between the three levels of the fair value hierarchy for the periods presented.

Valuation Methodologies Used to Measure Fair Value on a Non-Recurring Basis

Parent Guarantees and Bonds Associated with Balcke Dürr — In connection with the sale of Balcke Dürr, existing parent company guarantees and bank surety bonds, which totaled approximately Euro 79.0 and Euro 79.0, respectively, at the time of sale (and Euro 43.0 and Euro 28.7, respectively, at September 29, 2018) will remain in place through each instrument’s expiration date, with such expiration dates occurring through 2022. These guarantees and bonds provide protections for Balcke Dürr customers in regard to advance payments, performance, and warranties on projects in existence at the time of sale. In addition, certain bonds relate to lease obligations and foreign tax matters in existence at the time of sale. Balcke Dürr and the Buyer have provided us an indemnity in the event that any bank guarantees or bonds are called. Also, at the time of sale, Balcke Dürr provided cash collateral of Euro 4.0 and mutares AG provided a guarantee of Euro 5.0 as a security for the above indemnifications (Euro 3.5 and Euro 5.0, respectively, at September 29, 2018). In connection with the sale, we recorded a liability for the estimated fair value of the guarantees and bonds and an asset for the estimated cash collateral and indemnities provided. Summarized below are the liability and asset recorded at the time of sale, along with the change in the liability and the asset during the nine months ended September 29, 2018, and September 30, 2017.

___________________________

⁽¹⁾

In connection with the sale, we estimated the fair value of the existing parent company guarantees and bank and surety bonds considering the probability of default by Balcke Dürr and an estimate of the amount we would be obligated to pay in the event of a default. Additionally, we estimated the fair value of the cash collateral provided by Balcke Dürr and guarantee provided by mutares AG based on the terms and conditions and relative risk associated with each of these securities (unobservable inputs - Level 3).


⁽²⁾	We reduce the liability generally at the earlier of the completion of the related underlying project milestones or the expiration of the guarantees or bonds. We amortize the asset based on the expiration terms of each of the securities. We record the reduction of the liability and the amortization of the asset to “Other income (expense), net.”


⁽³⁾	The balance associated with the guarantees and bonds is reflected within “Other long-term liabilities,” while the balance associated with the indemnification assets is reflected within “Other assets.”

Goodwill, Indefinite-Lived Intangible and Other Long-Lived Assets — Certain of our non-financial assets are subject to impairment analysis, including long-lived assets, indefinite-lived intangible assets and goodwill. We review the carrying amounts of such assets whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable or at least annually for indefinite-lived intangible assets and goodwill. Any resulting asset impairment would require that the instrument be recorded at its fair value.

Valuation Methodologies Used to Measure Fair Value on a Recurring Basis

Derivative Financial Instruments — Our financial derivative assets and liabilities include interest rate swaps, FX forward contracts, FX embedded derivatives and commodity contracts, valued using valuation models based on observable market inputs such as forward rates, interest rates, our own credit risk and the credit risk of our counterparties, which comprise investment-grade financial institutions. Based on these inputs, the derivative assets and liabilities are classified within Level 2 of the valuation hierarchy. We have not made any adjustments to the inputs obtained from the independent sources. Based on our continued ability to enter into forward contracts, we consider the markets for our fair value instruments active. We primarily use the income approach, which uses valuation techniques to convert future amounts to a single present amount.

As of September 29, 2018, there has been no significant impact to the fair value of our derivative liabilities due to our own credit risk, as the related instruments are collateralized under our senior credit facilities. Similarly, there has been no significant impact to the fair value of our derivative assets based on our evaluation of our counterparties’ credit risks.

Indebtedness and Other — The estimated fair value of our debt instruments as of September 29, 2018 and December 31, 2017 approximated the related carrying values due primarily to the variable market-based interest rates for such instruments. See Note 11 for further details.

We prepared the condensed consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules and regulations, certain footnotes or other financial information normally required by accounting principles generally accepted in the United States (“GAAP”) can be condensed or omitted. The financial statements represent our accounts after the elimination of intercompany transactions and, in our opinion, include the adjustments (consisting only of normal and recurring items) necessary for their fair presentation.

Variable Interest Entity

We account for investments in unconsolidated companies where we exercise significant influence but do not have control using the equity method. In determining whether we are the primary beneficiary of a variable interest entity (“VIE”), we perform a qualitative analysis that considers the design of the VIE, the nature of our involvement and the variable interests held by other parties to determine which party has the power to direct the activities of the VIE that most significantly impact the entity’s economic performance, and which party has the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. We have an interest in a VIE, in which we are not the primary beneficiary, as a result of the sale of Balcke Dürr. See below and in Notes 3 and 16 for further discussion of the sale of Balcke Dürr. All other VIEs are considered immaterial, individually and in aggregate, to our condensed consolidated financial statements.

Acquisition

Acquisition of Cues

On June 7, 2018, we completed the acquisition of Cues, Inc. (“Cues”), a manufacturer of pipeline inspection and rehabilitation equipment, which significantly increases our presence in the pipeline inspection market. The acquisition was completed through the purchase of all of the issued and outstanding shares of Cues’ parent company for a purchase price of $166.2, net of cash acquired of $20.6. Cues had revenues of approximately $84.0 for the twelve months prior to the acquisition. The assets acquired and liabilities assumed have been recorded at preliminary estimates of fair value as determined by management, based on information currently available and on current assumptions as to future operations and are subject to change upon completion of acquisition accounting. The post-acquisition operating results of Cues are reflected within our Detection and Measurement reportable segment. See Note 3 for additional details on the Cues acquisition.

Acquisition of Schonstedt

On March 1, 2018, we completed the acquisition of Schonstedt Instrument Company (“Schonstedt”), a manufacturer and distributor of magnetic locator products used for locating underground utilities and other buried objects, for a purchase price of $16.4, net of cash acquired of $0.3. Schonstedt had revenues of approximately $9.0 for the twelve months prior to the acquisition. The assets acquired and liabilities assumed have been recorded at preliminary estimates of fair value as determined by management, based on information currently available and on current assumptions as to future operations, and are subject to change upon completion of acquisition accounting. The post-acquisition operating results of Schonstedt are reflected within our Detection and Measurement reportable segment.

Sale of Balcke Durr

Sale of Balcke Dürr

On December 30, 2016, we completed the sale of Balcke Dürr to a subsidiary of mutares AG (the “Buyer”). During the first quarter of 2017, we reduced the net loss associated with the sale of Balcke Dürr by $7.2, with such amount recorded to “Gain on disposition of discontinued operations, net of tax.” The reduction was comprised of an additional income tax benefit recorded for the sale of $8.4, partially offset by adjustments to liabilities retained in connection with the sale, net of tax, of $1.2. During the second quarter of 2017, we increased the net loss associated with the sale of Balcke Dürr by $0.4, with the increase resulting from adjustments to liabilities retained in connection with the sale.

On April 30, 2018, we reached a settlement with the Buyer on the amount of cash and working capital at the closing date, as well as on various other matters, for a net payment from the Buyer in the amount of Euro 3.0 (with Euro 2.0 received in May 2018 and Euro 1.0 in July 2018). The settlement resulted in a gain, net of tax, of $3.8, which was recorded to “Gain (loss) on disposition of discontinued operations, net of tax” during the second quarter of 2018. See Note 3 for information on discontinued operations.

Use of Estimates

Preparing financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Actual results could differ from these estimates. The unaudited information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2017. Interim results are not necessarily indicative of full year results. We have reclassified certain prior year amounts to conform to the current year presentation. Unless otherwise indicated, amounts provided in these Notes pertain to continuing operations only. See Note 3 for information on discontinued operations.

Fiscal Period

We establish actual interim closing dates using a fiscal calendar, which requires our businesses to close their books on the Saturday closest to the end of the first calendar quarter, with the second and third quarters being 91 days in length. Our fourth quarter ends on December 31. The interim closing dates for the first, second and third quarters of 2018 are March 31, June 30 and September 29, compared to the respective April 1, July 1 and September 30, 2017 dates. We had one less day in the first quarter of 2018 and will have one more day in the fourth quarter of 2018 than in the respective 2017 periods. We do not believe the one less day during the first quarter of 2018 had a material impact on our consolidated operating results for the first nine months of 2018, when compared to the consolidated operating results for the first nine months of 2017.

New Accounting Pronouncements

NEW ACCOUNTING PRONOUNCEMENTS

The following is a summary of new accounting pronouncements that apply or may apply to our business.

ASC Topic 606

Summarized below is the impact of the initial application of ASC 606 on our January 1, 2018 condensed consolidated balance sheet:



	December 31, 2017			Impact of Adoption of ASC 606			January 1, 2018

Assets
Accounts receivable, net	$	267.5		$	(36.0	)	$	231.5

Other Accounting Pronouncements

Goodwill and Other Intangible Assets

Currency Forward Contracts and Currency Forward Embedded Derivatives

From time to time, we enter into forward contracts to manage the exposure on contracts with forecasted transactions denominated in non-functional currencies and to manage the risk of transaction gains and losses associated with assets/liabilities denominated in currencies other than the functional currency of certain subsidiaries (“FX forward contracts”). In addition, some of our contracts contain currency forward embedded derivatives (“FX embedded derivatives”), because the currency of exchange is not “clearly and closely” related to the functional currency of either party to the transaction. Certain of our FX forward contracts are designated as cash flow hedges. To the extent these derivatives are effective in offsetting the variability of the hedged cash flows, changes in the derivatives’ fair value are not included in current earnings, but are included in AOCI. These changes in fair value are reclassified into earnings as a component of revenues or cost of products sold, as applicable, when the forecasted transaction impacts earnings. In addition, if the forecasted transaction is no longer probable, the cumulative change in the derivatives’ fair value is recorded as a component of “Other income (expense), net” in the period in which the transaction is no longer considered probable of occurring. To the extent a previously designated hedging transaction is no longer an effective hedge, any ineffectiveness measured in the hedging relationship is recorded in earnings in the period in which it occurs.

Potential Uncertain Positions

We perform reviews of our income tax positions on a continuous basis and accrue for potential uncertain positions when we determine that an uncertain position meets the criteria of the Income Taxes Topic of the Codification. Accruals for these uncertain tax positions are recorded in “Income taxes payable” and “Deferred and other income taxes” in the accompanying condensed consolidated balance sheets based on the expectation as to the timing of when the matters will be resolved. As events change and resolutions occur, these accruals are adjusted, such as in the case of audit settlements with taxing authorities.

The Internal Revenue Service (“IRS”) currently is performing an audit of our 2014 and 2015 federal income tax returns. We have filed our federal income tax returns for the 2016 and 2017 tax years and those returns are also subject to examination. With regard to all open tax years, we believe any contingencies are adequately provided for.

State income tax returns generally are subject to examination for a period of three to five years after filing the respective tax returns. The impact on such tax returns of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. We have various state income tax returns in the process of examination. We believe any uncertain tax positions related to these examinations have been adequately provided for.

We have various foreign income tax returns under examination. The most significant of these are in Germany for the 2010 through 2014 tax years. We believe that any uncertain tax positions related to these examinations have been adequately provided for.

An unfavorable resolution of one or more of the above matters could have a material adverse effect on our results of operations or cash flows in the quarter and year in which an adjustment is recorded or the tax is due or paid. As audits and examinations are still in process, the timing of the ultimate resolution and any payments that may be required for the above matters cannot be determined at this time.

Fair Value


•	Level 1 — Quoted prices for identical instruments in active markets.


•	Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.


•	Level 3 — Significant inputs to the valuation model are unobservable.

⁽²⁾	We reduce the liability generally at the earlier of the completion of the related underlying project milestones or the expiration of the guarantees or bonds. We amortize the asset based on the expiration terms of each of the securities. We record the reduction of the liability and the amortization of the asset to “Other income (expense), net.”


⁽³⁾	The balance associated with the guarantees and bonds is reflected within “Other long-term liabilities,” while the balance associated with the indemnification assets is reflected within “Other assets.”
